Design

Score components:
JBL E25BT Design Picture

The JBL E25BT have a simple and easy-to-use wireless design, with a decently comfortable in-ear fit, and small earbuds that are very breathable. They also have a slightly better build quality than similarly designed headphones that we've tested recently like the Skullcandy Jib and the Sony WI-C300. Unfortunately, they do not come with any stability fins and also have an extra module on their cable that makes them slightly less stable than more typical in-ears.  On the upside, it's decently flat and comes with a cable management clip so it won't be as bothersome when tucked under a shirt or clipped to your clothes. They also have a good control scheme with a 3-button set up that's efficient, has good feedback, and provides all the essential functions. Overall they are portable, breathable and stable enough to be a decent option for sports.

Style
JBL E25BT Design Picture 2

The JBL E25BT have a similar look and feel to some of the other wireless in-ears that we've tested recently like the Skullcandy Jib and the Sony WI-C300. They have a simple and straightforward wireless in-ear design, with a thin audio cable that has an additional module to house the battery. The earbuds are small and do not come with any stability fins or ear-hooks which makes them compact but also look a bit cheap. On the upside, the battery module on the back of the cable is a little flatter and slightly smaller than that of the Skullcandy Jib or the WI-C300 so it won't be as bothersome during physical activity, although the design will not be for everyone. They also come in a few color schemes that are a bit more distinguishable at a distance than the Jib so you can better match your headphones to your clothing.

7.0 Comfort
What it is: Adjustability and degrees of freedom, pressure, stiffness and weight.
When it matters: When the headphones are going to be used for long durations.
Score components: Subjectively assigned
JBL E25BT Comfort Picture
Weight : 0.06 lbs
Clamping Force
What it is: The force that the headphones exert on your head, once you have them on. This is purely a measurement of the force applied, which does not take into account the earpad's surface area and the resulting pressure you will feel, on or around your ears.
When it matters: The tighter the headphones, the more force they put on your head. This can get uncomfortable or cause pain and soreness during long listening sessions.
:
0 lbs

The JBL E25BT are decently comfortable wireless in-ears similar to the Skullcandy Jib and the Sony WI-C300. They have a similar earbud design that's very small and does not have many points of contact with the outer parts of your ear canal, which makes them a bit more comfortable than conventional in-ears. However they do not come with as many tip options as some of the more premium in-ears we've tested like the 1More Triple Driver In-Ear, so they won't be as comfortable for everyone. Also, like the WI-C300 and the Jib, they have a bulky module on the back of the cable that may get a bit bothersome since it will bounce up and down when running unless you tuck it into your shirt or attach it to your clothing with the additional neck clip provided in the box.

7.4 Controls
What it is: The control scheme of the headphones, the number of functions provided, button layout and ergonomics as well as the quality of tactile feedback.
When it matters: If you want to control volume, pause your music or make phone calls without directly interacting with your audio device.

What it is: How hot the headphones get when you wear them for an extended period of time.
When it matters: If you often have long listening sessions or use your headphones while doing physical activities like running or working out.
Score components:
JBL E25BT Breathability After Picture
Avg.Temp.Difference : 0.8 C

The JBL E25BT are very breathable headphones like most in-ears. They do not touch or cover any parts of your outer ear, so your ears will remain cool no matter the physical activity. Their earbuds are also a bit smaller than typical in-ears, so they barely cause any temperature difference when running and working out. This makes them a decent option for most sports.

8.8 Portability
What it is: The volume of space occupied by the headphones when folded into their most compact format.
When it matters: If you're often on the move and need to carry your headphones in a bag, purse , or pocket.

Stand required : N/A

The JBL E25BT are very portable headphones that will easily fit into your pockets. Their earbuds are smaller than typical in-ear designs, but since they have an additional module on their cable like the Skullcandy Jib they are slightly bulkier than wired in-ears and most truly wireless headphones. On the upside, they are still compact enough to easily carry on your person at all times.

5.5 Case
What it is: The provided carrying options to protect your headphones when transporting them.
When it matters: To prevent damaging your headphones, if you often carry them in your bag or pocket.

These headphones come with a small soft pouch similar to some of the Jaybird headphones. It's compact and portable enough to easily a carry on your person but does not offer as much protection for your headphones as a soft or hard case would.

6.5 Build Quality
What it is: Durability, material quality, cheap/expensive feel.
When it matters: When the headphones are going to be used by multiple users (classes/studios), by children, in tough conditions, on a daily basis, or for exercise.
Score components: Subjectively assigned
JBL E25BT Build Quality Picture

The JBL E25BT have a slightly better build quality than similarly designed headphones like the Skullcandy Jib and the Sony WI-C300. The cables are coated with a more durable fabric than the other models, and the in-line remote and battery module feels better built with a slightly more high-end plastic. The earbuds unfortunately still look and feel a bit cheap, and their overall design won't be as durable as some of the other wireless in-ears and earbuds we've reviewed like the Bose SoundSport Wireless.

7.0 Stability
What it is: How the headphones are designed to prevent them from slipping off your ears or falling off your head.
When it matters: If you plan on using the headphones while doing sports or other physical activities that requires a lot of movement.
Score components: Subjectively assigned
JBL E25BT Stability Picture

The JBL E25BT have are decently stable wireless in-ears. However, they have have a fairly bulky module on their audio cable that bounces around when running, if not tucked under your shirt or clipped to your clothes, with the additional neck clip provided in the box. It pulls slightly on the earbuds making them a bit less stable than other wireless in-ears with a similar design like the Jaybird Freedom. They also do not come with any additional stability fins so they may occasionally slip out of your ears during more strenuous workouts.

Sound

What it is: How accurately the audio is reproduced. The tests are performed with the headphones' most commonly used features enabled (noise-cancelling, wireless, etc.)
JBL E25BT Frequency Response

The JBL E25BT is a decent sounding pair of closed-back in-ear headphones. They have a deep, powerful, and consistent bass, and even mid-range, and a well-balanced treble. However, their bass is slightly muddy, their mid-range is a bit recessed, and their treble could be a little sharp on S and T sounds. Overall, they are a versatile pair of headphones and suitable for a wide variety of genres, from bass-heavy music to rock, and pop. However, they may not be ideal for classical and vocal-centric music.

8.1 Bass
What it is: Frequency Response from 20Hz-250Hz
When it matters: When the material is heavy on bass frequencies, such as those of kick drums and bass guitar.
Score components:
JBL E25BT Bass
Std. Err.
What it is: The amount of deviation (weighted standard error) in bass frequency response (20Hz-250Hz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) bass performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
2.81 dB
Low-Frequency Extension
What it is: The lowest frequency at which the frequency response reaches -3dB of the target response.
When it matters: Shows how extended the bass is.
Good value: <40Hz
Noticeable difference: 5Hz
:
10 Hz
Low-Bass
What it is: The average amount of over/under-emphasis in frequency response from 20Hz-60Hz.
When it matters: Kick drums and low frequency effects get their 'thump' from this range. Mostly felt than heard.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
1.23 dB
Mid-Bass
What it is: The average amount of over/under-emphasis in frequency response from 60Hz-120Hz.
When it matters: Melodic bass instruments have most of their fundamental frequencies in this range. This is where the 'body' and 'punch' of the bass sits.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
2.59 dB
High-Bass
What it is: The average amount of over/under-emphasis in frequency response from 120Hz-250Hz.
When it matters: Most instruments get their warmth and full-ness from this range. When over-emphasized, mixes tend to get muddy and boomy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
4.35 dB

The bass is great. LFE (low-frequency extension) is at 10Hz, which is excellent. Low-bass, responsible for the thump and rumble common to bass-heavy music is within 1dB of our neutral target. This results in a sub-bass that is extended and has just the right amount of thump to it. Mid-bass, responsible for the body of the bass guitars and the punch of the kick drums is hyped by less than 3dB. High-bass, responsible for warmth, is overemphasized by more than 4dB. This makes the overall bass a bit boomy and muddy.

7.5 Mid
What it is: Frequency Response from 250Hz-2KHz
When it matters: When the material is heavy on mid-range frequencies. This is the case for the majority of audio content.
Score components:
JBL E25BT Mid
Std. Err.
What it is: The amount of deviation (weighted standard error) in mid frequency response (250Hz-2.5KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) mid performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
3.36 dB
Low-Mid
What it is: The average amount of over/under-emphasis in frequency response from 250Hz-500Hz.
When it matters: Most instruments have their fundamentals or low harmonics in this range. Over-emphasis in this range sounds muddy and cluttered. Under-emphasis, thins out the vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
1.36 dB
Mid-Mid
What it is: The average amount of over/under-emphasis in frequency response from 500Hz-1KHz.
When it matters: This range is occupied mostly by upper harmonics. Over-emphasis sounds forward and boxy. Under-emphasis pushes instruments to the back of the mix.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-4.17 dB
High-Mid
What it is: The average amount of over/under-emphasis in frequency response from 1KHz-2KHz.
When it matters: Most instruments, especially vocals, get their intensity and clarity from this range. Over-emphasis sounds honky and harsh, under-emphasis sounds weak and distant.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-3.18 dB

The JBL E25BT have a good mid-range performance. Low-mid shows the continuation of the high-bass bump. This thickens the vocals a bit and makes mixes a bit cluttered. However, at 1.4dB this effect will be quite subtle. The dip in mid-mid and high-mid makes the mid-range a bit recessed by pushing vocals and lead instruments towards the backs of the mix and gives more emphasis to the lower frequencies.

8.0 Treble
What it is: Frequency Response from 2KHz-20KHz
When it matters: When the material is heavy on high-range frequencies, such as voice, cymbals, and any other material where brightness, brilliance and airiness is desired.
Score components:
JBL E25BT Treble
Std. Err.
What it is: The amount of deviation (weighted standard error) in treble frequency response (2.5KHz-20KHz) as compared to a target response that would sound perfectly balanced to most people.
When it matters: When a balanced and neutral (reference) treble performance is desired.
Good value: <4dB
Noticeable difference: 0.1dB
:
3.43 dB
Low-Treble
What it is: The average amount of over/under-emphasis in frequency response from 2KHz-5KHz.
When it matters: Almost all instruments rely on this range for their presence, detail, and articulation. Over-emphasis can sound harsh and painful. Under-emphasis hurts the comprehensibility of vocals and lead instruments.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-2.16 dB
Mid-Treble
What it is: The average amount of over/under emphasis in frequency response from 5KHz-10KHz.
When it matters: This is the sibilance range. Cymbals, vocals, and lead instruments rely on this range for brightness and presence. Over-emphasis sounds piercing and painful, under-emphasis sounds dull and lispy.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
1.1 dB
High-Treble
What it is: The average amount of over/under-emphasis in frequency response from 10KHz-20KHz.
When it matters: This range gives brilliance and airiness to the sound. Over-emphasis sounds hissy, under-emphasis sounds closed-up and lifeless.
Good value: +/-3dB
Noticeable difference: 0.1dB
:
-1.32 dB

The JBL E25BT have a very good treble. Low-treble is even and balanced, but underemphasized by about 2dB. This has a subtle but negative effect on brightness and detail of vocals and lead instruments. Mid-treble is a bit uneven, especially around 10KHz. This could translate into uneven sibilances, that is, some and S and T sounds may be overemphasized and some other may be underemphasized.

Raw Frequency Response
What it is: The average uncompensated frequency response of the headphone. For in-ears and earbuds, this corresponds to the average of 5 measurements/re-seats on the dummy head (HMS). For over/on-ear headphones, this corresponds to the average of 5 measurements/re-seats on the HMS (Head Measurement System) for the mid and treble ranges, and 5 measurements/re-seats on 5 human subjects for the bass range.
When it matters: This is for those who want to see the raw and uncompensated frequency response of the headphone. Some of the more advanced users, are able to read and evaluate headphone frequency response in its raw form and without compensation. This will be especially useful to them if they have their own headphone compensation/target curve, which may differ from the compensation curve/target response used by RTINGS.com.
Score components:
9.7 Frequency Response Consistency
What it is: The amount of deviation of each frequency response pass, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Score components:

Avg. Std. Deviation
What it is: The average amount of deviation in frequency response of 5 re-seats, from the average frequency response.
When it matters: Shows how consistently the headphones perform after re-positioning them.
Good value: <0.5
Noticeable difference: 0.1
:
0.07 dB

The frequency response consistency of the JBL E25BT is excellent. If the user is able to achieve a proper fit and an air-tight seal using the assortment of tips that come with the headphones, then they should be able to get consistent bass and treble delivery every time they use the headphones.

9.4 Imaging
What it is: Imaging qualities are inherent to the audio content, the headphones have to 'reproduce' them rather than 'create' them. They determine how accurately the objects are positioned in the stereo image, and how transparent the imaging is.
When it matters: When accurate positioning of the objects in the stereo image, and clear and transparent imaging is desired.
JBL E25BT Group Delay JBL E25BT Phase Response
Weighted Group Delay
What it is: The average amount of group delay calculated based on a perceptual weighting filter. Group delay indicates how long it takes for each frequency to reach their maximum amplitude. This is a monaural quality and can be perceived even with one ear.
When it matters: Headphones with lower group delay have more transparent imaging and a tighter bass. Headphones with higher group delay in the bass range tend to have a wimpy and loose bass, and headphones with higher group delay in the treble range tend to have a less transparent imaging.
Good value: <0.5
Noticeable difference: 0.1

Weighted Amplitude Mismatch
What it is: The Left/Right balance of our test unit, that is, the amount of amplitude difference between the left and right drivers. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When a properly balanced stereo image and low manufacturing tolerance is desired. A poor score indicates a noticeable difference in level between the left and right drivers.
Good value: <1.5
Noticeable difference: 0.1

Weighted Frequency Mismatch
What it is: The amount of difference (Std. Err.) between the frequency response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When an even and stable stereo image, as well as a low manufacturing tolerance, is desired. A poor score indicates there may be 'holes' in the stereo image at certain frequencies.

Weighted Phase Mismatch
What it is: The amount of difference (Std. Err.) between the phase response of the left and right drivers of our test unit. This is not a design test, but a marker for manufacturing tolerance and ergonomics.
When it matters: When an even and stable stereo image, as well as a low manufacturing tolerance is desired. A poor score indicates there may be inaccuracies in the stereo image reproduction at certain frequencies.
Good value: <16
Noticeable difference: 3
:
1.23

The imaging performance is excellent. The weighted group delay is at 0.15, which is very low. The GD graph also shows that the entire group delay response is below the audibility threshold. This ensures a tight bass and a transparent treble reproduction. Additionally, the L/R drivers of our test unit were very well-matched, which is important for the accurate placement and localization of objects (instruments, voice, footsteps), in the stereo image.

1.4 Soundstage
What it is: Soundstage qualities are not inherent to the audio content, the headphones have to 'create' them rather than 'reproduce' them. They determine whether the sound is perceived to be coming from inside or in front of the head, how open and spacious the soundstage is, how much the headphones acoustically interact with the environment, and how strong the phantom center is.
When it matters: When an accurately produced, large and spacious soundstage, similar to that of a stereo loudspeaker setup is desired.
PRTF Accuracy (Std. Dev.)
What it is: The standard deviation of the PRTF (Pinna-related transfer function) of the headphones compared to a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: An accurate pinna activation is mainly responsible for how natural and speaker-like the soundstage is perceived to be. The less error in the shape of the PRTF, the more natrual and speaker-like the perception of the soundstage will be. High amounts of error may indicate a soundstage that is unnatural or odd.
Good value: <2.5
Noticeable difference: 0.1

PRTF Size (Avg.)
What it is: The average amplitude of the PRTF (Pinna-related transfer function) of the headphones compared to that of a reference loudspeaker's PRTF at 30°. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is responsible for the perceived size of the soundstage. The higher the value, the larger the perceived size of the soundstage. However, values above the reference (5.0dB) could result in a soundstage that is perceived as unnatural or odd.
Good value: >3.7

PRTF Distance
What it is: The depth of the "10KHz notch" of the headphone's PRTF, which is caused by phase cancellations at the concha. This quality is monaural and can be perceived even with one ear. This test does not apply to in-ears and earbuds, due to the lack of pinna interaction.
When it matters: This value is mainly responsible for the perceived distance and elevation of the soundstage. A small distance value may result in a soundstage that is perceived to be located inside the head. Larger values may help pull the soundstage out from inside of the head and bring it to the front.
Good value: >13
Noticeable difference: 1

N/A
Openness
What it is: How open the headphones are, and how open and spacious they sound. This quality is monaural and can be perceived even with one ear. This test differentiates between acoustically and electronically produced crosstalk and only takes the acoustically generated crosstalk into account. This value is the inverse of the Noise Isolation test score, and could be indirectly related the acoustic impedance of the headphones.
When it matters: When a headphone with a sense of an open, and spacious soundstage is desired. A value of 10 indicates a fully open headphone, and a value of 0 indicates a fully closed headphone.
Good value: >7.5
Noticeable difference: 0.5
:
3.7
Acoustic Space Excitation
What it is: How loud the headphones are, and how much they excite their environment acoustically. If the headphones are loud and open enough, the sound leaking from the headphones will be affected by the environment (reflections/reverb) before reflecting back into the open headphones and to the listener's ears. This quality is monaural and can be perceived even with one ear. This value is the inverse of the Leakage test score.
When it matters: Headphones with higher excitation values, similar to openness, tend to have soundstages that are perceived as more open and spacious.
Good value: >7.5
Noticeable difference: 0.5
:
1.6
Correlated Crosstalk
What it is: How strong and solid the phantom center is. This is mostly a stereo quality and its effects on mono content are minimal. This test is sensitive to the phase of the crosstalk and whether it is produced acoustically or electronically.
When it matters: When a true reproduction of the stereo image is desired. A value of 0 indicates no crosstalk, or that the existing crosstalk is not correlated enough to affect the phantom center. A negative score means the crosstalk is out of phase with the original signal, resulting in a slightly wider stereo image at the expense of creating a 'hole' at the center of the stereo field. A positive score means the crosstalk is in phase and positively affecting the phantom center.
Good value: >1dB
Noticeable difference: 0.3dB
:
0.0 dB

The soundstage of the JBL E25BT Wireless is poor. This is because creating an out-of-head and speaker-like soundstage is largely dependent on activating the resonances of the pinna (outer ear). The design of in-ears and earbuds is in such a way that fully bypasses the pinna and doesn't interact with it. Also, because these headphones have a closed-back enclosure, their soundstage won't be perceived to be as open as that of open-back earbuds like the Apple AirPods, Google Pixel Buds, or the Bose SoundSport Free.

7.6 Total Harmonic Distortion
What it is: The subtle, unwanted frequencies (harmonics) produced alongside the intended frequencies.
When it matters: When clean and pure sound reproduction is desired, though its effect is not as noticable as frequency response.
Score components:
JBL E25BT Distortion
Weighted THD @ 90
What it is: The overall amount of harmonic distortion measured at 90dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at moderate listening levels.
Good value: <0.100
Noticeable difference: 0.1

Weighted THD @ 100
What it is: The overall amount of harmonic distortion measured at 100dB SPL. To make the score more perceptually relevant, more weight is given to the higher frequencies.
When it matters: How pure the sound is at loud listening levels.
Good value: <0.300
Noticeable difference: 0.1
:

The JBL E25BT have a good harmonic distortion performance. The overall amount of THD in the bass range is very low, which is great. However, there is a bit of increase in THD in the mid and treble ranges, especially around 3KHz, which could make the sound of that region a bit impure.

7.0

Isolation

Score components:

The JBL E25BT deliver a decent noise isolation performance and have low leakage. They won't be the ideal choice for very noisy environments since they only provide passive isolation against ambient noise. They won't block the rumbling sounds of an engine, and loud ambient chatter will still seep into your audio. But on the upside, since they barely leak you can further mask ambient noise by playing your music at higher volumes without distracting the people around you.

6.2 Noise Isolation
What it is: How much outside noise is blocked out by putting the headphones on.
When it matters: If the headphones are going to be used in a noisy envinronment (airplane, subway, etc.)

The isolation performance is about average. Although these headphones don't have active noise cancelling, they were able to achieve about 6dB of isolation in the bass range. However, this won't be quite adequate for reducing the rumble of airplane and bus engines that occupy that frequency range. In the mid-range, important for blocking out speech, they isolate by more than 18dB, which is good. In the treble range, occupied by sharp sounds like S and Ts, they achieved more than 31dB of isolation, which is good.

8.6 Leakage
What it is: The amount of sound bleeding out of the headphones.
When it matters: When the listener doesn't want people around them (in office, recording studio, etc.) to hear what is being listened to.

Good value: >3.5dB
Noticeable difference: 0.5dB
:
2.19 dB
HFE
What it is: High-frequency extension is the highest frequency at which the frequency response reaches -3dB of the target response. It shows how extended the treble response of the microphone is.
When it matters: HFE is one the most important factors in speech intelligibility. The higher the HFE, the brighter, more open, and more extended the speech quality will be which makes it a lot easier to understand by the listener.
Good value: >8KHz

Good value: >18dB
Noticeable difference: 3dB
:
1.68 dB

The microphone of the JBL E25BT has a sub-par recording quality. The LFE (low-frequency extension) of 479Hz means speech recorded/transmitted with this mic will sound relatively thin. The HFE (high-frequency extension) of 2.4KHz results in a speech that is muffled and lacks quite a bit of detail. This will have a small negative effect on the intelligibility of speech. However, the response between the LFE and HFE points is good.

7.5 Noise Handling
What it is: How well the microphone is able to separate speech from background noise, so that the transmission would include more voice and less noise.
When it matters: When a clean and intelligible speech transmission is desired in a noisy situation like talking on the phone on a busy street or on the bus.

What it is: Speech to Noise Ratio is the difference in level between speech and background noise as heard by the listener
When it matters: If the microphone is going to be used in a noisy environment, it is important for it to be able to separate the speech from background noise, so the voice would be easily audible and understandable.
Good value: >24dB
Noticeable difference: 3dB
:
23.93 dB

The noise handling of the microphone is good. It achieved a speech-to-noise ratio of 24dB in our SpNR test. This means they are able to separate speech from ambient noise to a good degree in moderately loud environments, like a busy street but may struggle in louder situations, like a subway station.

Compared to other Headphones

JBL E25BT Compare Picture

The JBL E25BT have a simple and straightforward wireless in-ear design that's decent enough for most use cases. They have a moderately balanced audio reproduction that will sound good enough for most listeners and a decently long battery life that will last you a full workday. They're easy to use with a good control scheme and a slightly more comfortable in-ear fit than typical in-ear designs, thanks to their small earbuds. Unfortunately, they do not come with a lot of tip options,  their build quality though better than some similarly designed models, still feels a bit cheap, and they do not block noise well enough to be the ideal option for commuting. On the upside, their low leakage does help since you can mask a lot of ambient noise the louder you play your music. See our recommendations for the best budget earbuds, the best Bluetooth earbuds under $50 and the best wireless earbuds for iPhone.

Sony WI-C300

The JBL E25BT are better headphones overall than the Sony WI-C300. The JBLs also have a higher-end build quality and a flatter battery module with better cable management. The E25BT also have a longer battery life and a more balanced sound with a deeper bass. The WI-C300, on the other hand, support NFC which makes them slightly easier to pair with mobile phones.

Beats BeatsX

The Beats X are better all-around headphones for most use cases than the JBL E25BT. The BeatsX have a better and more premium build quality, a much greater wireless range and very fast charge time. They also sound better than the E25BT overall, although they do struggle more with high frequencies. The JBLs, on the other hand, can pair with multiple devices at once for easy switching between Bluetooth sources and they have a longer battery life.

Jabra Elite 25e

The JBL E25BT are a slightly better headphone than the Jabra Elite 25e, but not by much. The JBl have a slightly more balanced sound than the 25e. The JBl also isolate a bit more in noisy environments, making them a bit better-suited for the commute and travel. They're also more potable than the Elite 25e. On the upside, the Elite 25e have a longer 16hr battery life, a more comfortable earbud fit, and a better control scheme, with a dedicated mic button. 

JBL Endurance Sprint

The JBL Endurance Sprint are slightly better headphones overall than the JBL E25BT. The Sprint have a better build quality and a more sports-oriented design with IPX7 water resistance. They also have a better-balanced sound and a more stable ear-hook design that will prevent the headphones from falling off your ears when running or doing more intense physical activities. The JBL E25BT, on the other hand, are more portable and have a better control scheme. They also deliver a slightly longer battery life on average although they do not have an auto-off feature so they won't last as long the Endurance Sprint.

Skullcandy Jib

The JBL E25BT are slightly better headphones than the Skullcandy Jib but not by much. The JBL have a better build quality and a longer lasting battery life. The E25BT also have a slightly better-balanced sound and better cable management so the module on the back of their cable will not bounce around as much if you use the clip. On the other hand, the Jib have a better mid-range and will not sound as sharp on some S and T sounds.

Jaybird Freedom

The Jaybird Freedom are much better headphones overall than the JBL E25BT. The Freedoms have more customization options, they're more comfortable and more suitable for sports thanks to their multiple tips and stability fins. The Jaybird also have better build quality than the JBLs. On the upside, the E25BT can pair with two devices simultaneously, so you can quickly switch between your phone and tablet. They also have a longer battery continuous battery life than the Jaybird Freedom and do not need a cumbersome charging clip.

Conclusion

6.7Mixed Usage
What it is: This is the combination of the different use cases to evaluate how versatile the headphones are. Therefore an everyday headphone should be well-rounded enough to adapt to most situations and environments without significant losses in sound quality, design ergonomics or isolation.
Score components:
Average for mixed usage. The JBL E25BT have an easy-to-use and wireless in-ear design that's lightweight and portable. They sound good enough for most and have very low leakage and somewhat okay noise isolation to be a decent option for commuting, sports, and the office. Unfortunately, they lack customization options, they feel slightly cheap, and since they are Bluetooth-only headphones, you will not be able to use them passively if the battery dies and their wireless latency will not be ideal for watching movies and gaming.
6.8Critical Listening
What it is: The level of audio fidelity a headphone can reproduce. Therefore a balanced and true representation of bass, mids, treble, soundstage and imaging, as well as a comfortable listening experience, is essential for critical listening.
Score components:
Decent for critical listening. They have a good bass range that will sound punchy and exciting with most tracks, if a little boomy at times. They also have a decently balanced mid-range and won't sound too sharp with instruments and vocals like some of the other wireless in-ears we've tested. They should sound good and balanced enough for most, but more critical listeners may not like the small soundstage.
7.0Commute/Travel
What it is: How well the headphones handle the loud environments involved in commuting or traveling. Therefore your listening experience should be comfortable, hassle-free and as isolated from noise as possible.
Score components:
Decent for commuting. They're compact and fit into most pockets. They also have a good control scheme that you can use on the go with your phone. They do not block as much noise as typical in-ear designs but since they barely leak even at high volumes you can mask some of the ambient noise with your music without distracting anyone around you.
7.7Sports/Fitness
What it is: How well-adapted the headphones are, to use while doing sports or strenuous exercise. Therefore the headphones should not be too cumbersome and deliver a stable and comfortable listening experience.
Score components:
Above-average for sports. These headphones have a decently stable in-ear fit, they're wireless and small enough to carry around on your person wherever you go. They also have a good and easy to use control scheme, but unfortunately, the module on the back of the cable makes them slightly unstable, but the provided neck clip somewhat mitigates this issue if you attach it to the back of your shirt.
6.9Office
What it is: How well the headphones can deliver a comfortable and isolated listening experience in an office-like environment. They should not leak much and should block the noise of a busy office.
Score components:
Decent for office use. They barely leak even at high volumes so you can mask the ambient noise of a lively office by playing your music a little louder without distracting your colleagues. Unfortunately, they are not the most isolating in-ears we've tested so some noise will seep into your audio in loud environments.

Sub-par for home theater use. They have quite a bit of latency and no wired connection option. This means that they won't be ideal for watching video content and unfortunately, they're not the most comfortable headphones to wear for particularly long movies.
5.1Gaming
Score components:
Sub-par for gaming. They have a mediocre-at-best mic that will not be compatible with consoles. They lack customization options and have a bit too much latency to be a suitable choice for gaming.
